I forgot how to do an inverse search to find my ASN in as-sets.

So Google AI tells me:

Yet:

hank@nocvm:~$ whois -h whois.ripe.net -i members as378
% This is the RIPE Database query service.
% The objects are in RPSL format.

% The RIPE Database is subject to Terms and Conditions.

%ERROR:105: attribute is not searchable

% "members" is not an inverse searchable attribute.

%ERROR:101: no entries found

% No entries found in source RIPE.

% This query was served by the RIPE Database Query Service version 1.120 (DEXTER)

What am I doing wrong?

Thanks,

Hank
